White blood cell derived from bone marrow. As part of the immune system, B cells (or bursa‐equivalent cells) may differentiate and become antibody‐producing plasma cells. Also called B lymphocyte.
Lymphocytes that are part of the adaptive immune response and are responsible for the production of antibodies to a specific antigen.
A specialized lymphocyte that, upon stimulation by an antigen, releases a specific antibody, resulting in humoral immunity B lymphocyte.
Lymphocytes that arise in the bone marrow, and are present in the blood, lymph, and connective tissue.
A type of white blood cell; B lymphocyte. B cells are formed in the bone marrow and circulate in the blood and lymphatic system. They have an essential role in immunology. Many B cells mature into plasma cells, which manufacture antibodies, proteins necessary to fight infections. Other B cells mature into memory B cells that “remember” the antigen that originally stimulated them to mature. This allows the body to recognize the antigen as a foreign body if it reencounters it in the future and to make antibodies to destroy it. Once antibodies are formed, whenever the body is re-exposed to the same bacteria the body recognizes the infectious organism and starts making antibodies to combat it.
